Unemployment Rate vs S&P 500

UNRATE is the seasonally adjusted U-3 unemployment rate from the BLS Current Population Survey, published the first Friday of each month at 8:30am ET as part of the Employment Situation report. The household survey samples roughly 60,000 households, classifying each working-age adult as employed, unemployed, or not in the labor force. SPDR S&P 500 ETF (SPY) tracks the cap-weighted S&P 500, the benchmark for U.S. large-cap equity claims on the underlying economy.

The two are connected through the corporate-profits-share-of-GDP channel and through Fed policy reaction. Rising unemployment historically signals slower wage growth, which compresses input costs and can preserve margins; it also signals slower aggregate demand, which compresses revenue. The net effect on S&P 500 earnings depends on which channel dominates. Federal Reserve research (Gertler and Karadi 2015, working paper series) documents that the Fed's response function shifts when U-3 rises through the natural rate, and rate cuts then become a tailwind for SPY multiples. The Sahm Rule is the formal trigger that captures this transition.

U-3 rose from 3.4% in January 2023 to 4.3% in July 2024. The Sahm Rule three-month-moving-average minus trailing-12-month-minimum measure crossed +0.53 percentage points in July 2024, triggering the recession indicator. In all 11 recessions since 1950, the Sahm Rule fired during the recession with a median lead of three months before NBER's official declaration. The 2024 trigger has now been outstanding for over 21 months without a recession declaration, the longest open trigger in the rule's history.

SPY ignored the trigger entirely. SPY closed July 31, 2024 at 549.84 and ended 2024 at 588.22 for a +24.0% calendar-year total return. The decoupling reflects three structural factors. First, the AI capex cycle drove S&P 500 earnings upward independent of broad labor-market conditions: Magnificent 7 companies represented roughly 32% of SPY weight in 2024 and contributed disproportionately to earnings growth. Second, Fed easing began September 2024 (50bp cut at the September 18 FOMC, two additional cuts to year-end totaling 100bp from the 5.25 to 5.50% peak), which supported multiple expansion. Third, U-3 remained low in absolute terms (4.3% versus the post-2009 trough of 3.4% but well below the historical natural-rate estimate of 5.0 to 5.5%).

The 2008 to 2009 episode is the clearest. U-3 rose from 5.0% in December 2007 to 10.0% in October 2009, a 500bp climb. SPY fell from a peak of 156.93 on October 9, 2007 to a trough of 67.10 on March 9, 2009, a -57.3% drawdown. SPY bottomed roughly seven months before U-3 peaked, the standard relationship in which equity markets price the recovery before the labor-market damage fully materializes.

The 2020 COVID episode compressed the same dynamic into weeks. U-3 rose from 3.5% in February 2020 to 14.7% in April 2020, an 1,120bp surge as 22 million payroll jobs were lost. SPY fell from 339.08 on February 19, 2020 to 218.26 on March 23, 2020, a -34.1% drawdown over 33 days. Federal Reserve emergency action ($1.6 trillion of Treasury purchases over three weeks plus the CARES Act fiscal impulse of $2.2 trillion) drove SPY to recover its pre-crisis level by mid-August 2020 while U-3 was still at 8.4%. The 2001 dot-com episode is the longest historical decoupling: SPY peaked September 2000, U-3 troughed at 3.9% in December 2000 and rose to 6.3% by June 2003, with SPY drawdown peaking at -49% in October 2002.

Convex Risk Appetite Index (CRAI), built from VIX, ICE BofA HY OAS, and equity put-call ratios, is the cleanest cross-check on whether SPY is correctly ignoring an UNRATE rise or whether the labor-market signal will eventually pull equities lower. In 2007, SPY peaked October 9 with CRAI in its top quartile, but CRAI began deteriorating in November 2007 well before SPY broke down in early 2008. The CRAI-conditioned read of the UNRATE-SPY pair would have flagged the 2008 setup three to four months earlier than the SPY price action alone.

The 2024 Sahm Rule trigger had a different CRAI signature. CRAI remained in its upper half throughout the July 2024 to year-end window, consistent with SPY's continued advance. There was no CRAI deterioration to confirm the labor-market signal. That joint reading (UNRATE rising, SPY rising, CRAI stable) is what made 2024 unprecedented in the post-1990 history. The April 2026 reading shows U-3 hovering in the mid-4% range, SPY near all-time highs, and CRAI in the upper-half. The pair continues to disagree, with CRAI siding with SPY rather than UNRATE.

Claudia Sahm, the economist who created the rule while at the Federal Reserve Board (Sahm 2019, Brookings paper), publicly stated in August 2024 and again in 2025 that the 2024 trigger was likely a false positive. Her reasoning, summarized in Fortune and Bloomberg interviews and in her own Substack posts, focuses on three factors: labor force participation rose from 62.4% in early 2023 to 62.7% in mid-2024 as immigration and prime-age participation increased, which mechanically raises U-3 without requiring layoffs; payroll growth remained positive throughout the trigger window (averaging 144,000 per month over the trailing 12 months as of July 2024); and the rise in U-3 was driven more by labor supply expansion than by job destruction.

The Federal Reserve has implicitly endorsed Sahm's interpretation through its policy actions: the FOMC began cutting rates in September 2024 not because recession was imminent but because real rates were too restrictive given decelerating inflation. The 100bp of cuts through end-2024 and additional cuts through 2025 brought Fed Funds toward the 3.50 to 3.75% range by April 2026. SPY responded to the policy easing rather than to the Sahm trigger, which is consistent with the labor-supply-driven interpretation.

The pair currently sits in the most decoupled state in its post-1990 history. UNRATE around mid-4%, SPY near all-time highs, Sahm Rule trigger outstanding for 21 months. The two resolution paths historically have been: SPY drawdown that reconciles with the labor-market signal (1973, 1990, 2001, 2007), or UNRATE reversal that vindicates the equity market (1995 to 1996, 2003, possibly 2024 to 2026). The April 2026 configuration is closest to the 1995 to 1996 mid-cycle correction analog: Greenspan paused the 1994 hiking cycle, U-3 stabilized at 5.5%, SPY went on to triple over the following five years.

The trade structure for the divergence is asymmetric. SPY has limited upside from current valuations (Buffett Indicator at 226 to 230% of GDP per Wilshire data, the highest reading on record) and material downside if the Sahm trigger reasserts. The cleanest expression is to maintain core SPY exposure while adding tail hedges: SPY puts at 90% of spot strike, VIX call spreads, and gold (GLD) as a regime-change hedge. Position sizing should account for the unprecedented duration of the Sahm trigger; the longer it persists, the larger the eventual reconciliation if recession materializes.
